An ellipse is the set of all points in the plane, for each of which the sum of the distances to two given points F1 and F2 of the plane is constant, greater than the distance between F1 and F2.

The points F1 and F2 are called focuses of the ellipse, and the distance between them - the focal length.

Passing through the focus of the ellipse segment, the ends of which lie on the ellipse is called the major axis of the ellipse. The length of the major axis is equal to 2a.

Segment perpendicular to the major axis passing through the center point of the major axis whose ends lie on an ellipse is called the minor axis of the ellipse.

The point of intersection of the major and minor axes of the ellipse is called its center.

Segments, conducted from the center of the ellipse to the top on the major and minor axes are called, respectively, the major axis and minor axis of the ellipse, and are indicated by a and b.

The area of an ellipse calculated by the formula: P=πab
